Chemical Structure
Description
4-Methoxy-3-(tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde (CAS 443776-90-7), molecular formula C14H19BO4 and molecular weight 262.11 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4-Methoxy-3-(tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
